Superconducting Resonators with Voltage-Controlled Frequency and Nonlinearity
Superconducting Resonators with Voltage-Controlled Frequency and Nonlinearity
Voltage-tunable superconductor-semiconductor devices offer a unique platform to realize dynamic tunability in superconducting quantum circuits. By galvanically connecting a gated InAs-Al Josephson junction to a coplanar waveguide resonator, we demonstrate the use of a wide-range gate-tunable superconducting element. We show that the resonant frequency is controlled via a gate-tunable Josephson …
